New low‐density ceramic material for packing fractional distillation columns. II

Abstract

The paper compares the new, spherical, low‐density ceramic material described in Part I with other packing materials having different geometries. The increased separating power of the new material is due to different liquid flow patterns, spreadability, accessible surface area and surface morphology. Although each of these terms has a distinctive meaning which cannot be employed without some reference to the other two, the first three terms are often erroneously used interchangeably throughout the literature. In this paper, these terms are more accurately defined and used in accordance with experimental evidence.
